Air (diatomic, MW = 28.8664 g/ mol) in an automobile tire is maintained at a pressure of 220 ka (gage) in an environment where the atmospheric pressure is 94 kPa. The air in the tire is at the ambient temperature of 25°C. A 4-mm-diameter hole develops in the tire as a result of physical damage. Approximating the gas flow as isentropic, determine the initial mass flow rate (kg/min) of air through the leak. Check first for choking.
Water leaving a thermoelectric plant condenser at 36 °C enters a cooling tower at a mass flow rate of 3.6x107 kg/h. A flow of cooled water returns to the condenser from the tower at a temperature of 30 °C and with the same flow rate. Make-up water is added separately at 20°C. Atmospheric air is admitted to the cooling tower at 25 °C and with 36% relative humidity. Moist air leaves the tower at 90% relative humidity and 35°C.Determine the mass flow rate of dry air and make-up water, in kg/h. Neglect heat exchanges and fan power. Assume permanent regime.
A mixture of refrigerant-134a at 120 kPa enters an evaporator with quality 0.12 and leaves it as fully vaporized (quality equal to 1). The latent heat is provided by 16.4 kg/s of air entering in the device at 23 ºC and exiting at 7 °C. Assume constant specific heat of the air cp=1.005 kJ/(kg K). Calculate the mass flow rate of the refrigerant in kg/s to 2 decimal places.
Atmospheric air with an air flow rate of 200 liter/min and a dry bulb temperature of 35 °C and relative humidity of 40 % is cooled to 10 °C using an air conditioner. Determine: a) How much water per hour is removed from the air during the process; b) The cooling capacity of the air conditioner required to cool the air.

Water at a flow rate of 40 kg/s should be cooled from 40°C to 30°C in a humid cooling tower. Atmospheric air used in the cooling tower enters the cooling tower at 1 atmosphere pressure, 22°C dry bulb, 16°C wet bulb temperatures and 32°C temperature, 95% relative humidity. Calculate (a) the volumetric flow rate of the air at the entrance to the tower, (b) the mass flow rate of the conservation behaviors required for cooling, using the psychometric diagram.

Steam is to be condensed by direct injection of cold water. The steam enters the condenser at the rate of (450 kg/hr) with dryness fraction of (0.9) and pressure (1 bar). The estimated heat losses from the condenser to the surroundings is (8500 kJ/hr). If cold water enters at (15"C) and the mixture of condensate and cooling water is to leave at (95"C). Determine the required flow of cooling water.
